[Buildroot] [git commit] core/pkg-generic: check proper package installation

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=938f47c7e89362e7b824dbd0bd1ee9839d56d603
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Some packages misbehave, and install files in either $(STAGING_DIR)/$(O)
or in $(TARGET_DIR)/$(O) .

One common reason for that is that pkgconf now prepends the sysroot path
to all the paths it returns. Other reasons vary, but are mostly due to
poorly writen generic-packages.

And a new step hooks to check that no file gets installed in either
location, called after the install-target and install-staging steps.
